Using water as a coolant during grinding extends the life of the diamond coating, reduces dust, and produces a smoother finish on your lapidary material.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the difference between Style A and Style B grit sets?\u003c\/h4\u003e\n\u003cp\u003eA: Style A includes 120#, 400#, and 1200# grits, providing a full range from rough grinding to a fine, polished finish. Style B includes 80#, 240#, and 400# grits, which is better suited for heavier stock removal and medium-level grinding tasks.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Are these wheels compatible with standard flat lap machines?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, these 6-inch (150mm) diameter flat lap wheels are designed to fit standard flat lap and faceting machines that accept this disc size.
